Abstract
The invention discloses a new pattern spinning machined cradle middle-foot, which is characterized by the following: providing a spinning machine drafting cradle with more stable property; keeping jaw gauge stable by the controlling jaw pressure of flat spring connecting the head of the middle-foot. The cradle can keep the pressure and jaw stable for a long time in the spinning drafting course, which is important to keep and improve the spinning quality stable as well as practical value.
Description
Technical field
The present invention relates to a kind of fine spining machine reel cage.
Background technology
The reel cage that is used at present fine spining machine drawing-off pressurization both at home and abroad is a majority with the PK series reel cage of German Aktiebolaget SKF production and the YJ2 series reel cage of the imitated SKF of China, this kind reel cage ubiquity pressure stability is poor, top roller three axis and bottom roll three axis parallel degrees are poor, defectives such as nip gauge poor stability, the top-pin rack flat spring pressurized flat spring of aiding the border areas later on of reel cage median claw front head and control nipper pressure particularly, cause nipper pressure on the weak side, be unfavorable for the stable of nip gauge, as adopt novel double-short leather-ring drawing-off form influence bigger, therefore cause between ingot and the ingot difference big, harm stabilizing and increasing of cotton yarn quality.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of fine spining machine reel cage median claw for this reason, this fine spining machine can make nipper pressure strengthen with the reel cage median claw, is beneficial to the stable of nip gauge, can effectively improve the quality of cotton yarn.
The present invention for the technical scheme that solves its technical problem and adopt is: this fine spining machine reel cage median claw, comprise the median claw head before aid the border areas, sell flat spring on the pressurized of aiding the border areas before the median claw head.
The invention has the beneficial effects as follows: because the pressurized top-pin rack flat spring of before aiding the border areas, the pressurized fulcrum moves forward to the jaw direction, and move forward towards the flat spring front end again, nipper pressure is obviously increased, therefore reel cage is difficult for lifting controlling after the pressurization to sell, make nip gauge more stable, dwindle difference between ingot and the ingot, guarantee stabilizing and increasing of cotton yarn quality.Jaw is reliable and stable when designing reel cage on probation in spinning, the pressurized flat spring of aiding the border areas after having solved causes on the weak side, the last pin of nipper pressure to lift easily and causes the unsettled defective of nip gauge, difference is dwindled between ingot and the ingot when spinning, and cotton yarn quality obviously improves.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is reel cage pressurization drawing-off state diagram of the present invention;
Fig. 2 is former reel cage pressurization drawing-off state diagram;
Fig. 3 is a schematic diagram of the present invention;
Fig. 4 is that B-B among Fig. 3 is to cutaway view;
Fig. 5 is Fig. 3 left view
Among the figure: aid the border areas behind 1-reel cage median claw, the 2-median claw, aid the border areas before the 3-median claw, apron, 10-top roller axle core, O-pressurized fulcrum under the 4-top-pin rack flat spring, the last pin of 5-, 6-nip gauge piece, 7-downside pin, 8-upper leather ring, 9-
The specific embodiment
Embodiment: shown in accompanying drawing, the present invention is described further with embodiment, as follows for the ease of narrating existing division:
1. reel cage of the present invention pressurization drawing-off state (Fig. 1): the reel cage median claw 1 head 3 pressurized flat springs 4 of aiding the border areas in the past, pressurized fulcrum O reach, make pin 5 relative downside pins 7 produce pressure F1, nip gauge piece 6 makes the stable nip gauge of formation between the downside pin, and making has stable friction circle to distribute with the free speed change of control rove yarn drawing-off between upper leather ring 8 and the following apron 9.
2. reel cage of the present invention pressurization drawing-off state (Fig. 1) contrasts with former reel cage pressurization drawing-off state (Fig. 2): former reel cage drawing-off state (Fig. 2) the reel cage median claw 1 head 2 pressurized flat springs 4 of aiding the border areas later on that pressurize, move behind the pressurized fulcrum O, the pressure F2 that pin 5 relative downside pins 7 are produced is on the weak side, going up pin during use lifts easily, cause nip gauge to increase during drawing-off, influence descends cotton yarn quality to the control of rove yarn; Improve the pressurized fulcrum O reach of the novel reel cage pressurization drawing-off state in back (Fig. 1), obviously greater than L1/L2 in (Fig. 2), just F1 is obviously greater than F2 according to P1/P2 in the mechanics principle (Fig. 1).The present invention (Fig. 4) obviously increases by improving the back nipper pressure, and nip gauge is stablized during drawing-off, can improve cotton yarn bar evenness, reduce details, slubbing, cotton knot, broken end etc., make cotton yarn quality reach the purpose of high-quality.
Claims (1)
1. fine spining machine reel cage median claw, comprise the median claw head before aid the border areas, it is characterized in that: sell flat spring on the pressurized of aiding the border areas before the median claw head.
